NVe claim:

A fourth connecting rod wrench comprising' a short-armed L-shaped ratchet head whose vertical arm is provided with a short upstanding squared stub shaft for frictional reception in one end of an ordinary socket, the horizontal arm of said head being surrounded by a ratchet reversing sleeve, a rod having one rectilinear end portion in exial alinement with and secured directly to said horizontal arm of said head to rest and oscillate 'on the inner side of the crank case bottomand hold the head, stub shaft and rod against dropping from the socket, said rod being bent downwardly at right angles memes at a point spaced from said head to form a hand crank, said rod being then bent horizontally at right angles under said first named end ortion and then bent downwardly at right angles to form a second hand grip axially alined with said stub shaft, the rod at the lower end of the second hand grip being bent laterally first in one directionand then in the other to provide oppositely extending handles, all portions of said rod being in a common plane with the arms of said head and the axis of said stub shaft.

In testimony whereof we havenereunto aflixed our signatures.
